What happens when gasoline is used to power a vehicle?

A.
Energy is neither lost nor gained as it transforms from chemical, to heat, to mechanical energy.

B.
Energy is neither lost nor gained as it transforms from chemical, to potential, to electrical energy.

C.
Energy is gained as chemical energy transforms to heat energy but lost as heat energy transforms to mechanical.

D.
Energy is lost as chemical energy transforms to heat energy but gained as heat energy transforms to mechanical.

The answer should be A. Because the energy in gasoline is called chemical. When burned it is heat, Then to power a vehicle, it is mechanical energy. But I don't know whether the question wants to mean that the energy in the gasoline will not convert totally to the heat, so it will lose. But if think like this, when heat energy transform to mechanical, it will lose again. So I think the answer is A.
